Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541366, here are decompositions:

7 + 31541359 = 31541366
19 + 31541347 = 31541366
97 + 31541269 = 31541366
193 + 31541173 = 31541366
349 + 31541017 = 31541366
499 + 31540867 = 31541366
643 + 31540723 = 31541366
673 + 31540693 = 31541366

Showing the first eight; more decompositions exist.
